Fix action.yaml with missing input variable (#46)

* Fix action.yaml with missing input variable

This commit fixes the action.yaml with the missing input variable to
surpress the warning we were seeing when running the action

* Add ability to specify the deployment sha

If this workflow isn't being ran from the current branch (which is the
case when you have a workflow being triggered by chatops), we need to be
able to specify the current commit this workflow should report.
